Car boosts real well. Talked to Harry @ ZTuner, he said its tuned to run 18lbs on these turbos, but safely run at 15lbs right now. The car was dynoed at 440 something he said and he said it should be running fine, no worries. He tuned it for the high compression due to the heads and said not to worry about a main bearing knock - he said he has never heard of it. Pics up later.
